1. 1. Motivational aspects of test-taking : measuring test-taking motivation in Swedish national test contexts

   Författare :Eva Knekta; Hanna Eklöf; Anna Sundström; Rolf Vegar Olsen; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Test-taking motivation; Swedish national tests; validity; expectancy-value theory; task value; expectancies; young adolescents; self-report instrument; interview; structural equation modelling; test stakes; didactics of educational measurement; beteendevetenskapliga mätningar;

   Sammanfattning : The overall aim of the work underlying this thesis was to improve the understanding of students’ test-taking motivation in connection to achievement tests for young adolescents. The thesis includes four studies and a summary. All four studies explore test-taking motivation and are all connected to validity in one way of another. LÄS MER

3. 2. System-on-Chip Test Scheduling and Test Infrastructure Design

   Författare :Anders Larsson; Petru Eles; Zebo Peng; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; system-on-chip; core-based systems; test infrastructure; test scheduling; broadcasting; test set sharing; Computer science; Datavetenskap;

   Sammanfattning : There are several challenges that have to be considered in order to reduce the cost of System-on-Chip (SoC) testing, such as test application time, chip area overhead due to hardware introduced to enhance the testing, and the price of the test equipment. In this thesis the test application time and the test infrastructure hardware overhead of multiple-core SoCs are considered and two different problems are addressed. LÄS MER

   Sammanfattning : Chapter 2 analyses the relationship between capital structure and industry classification of Swedish firms. This study also analyses the determinants of the capital structure at the industry level. LÄS MER

5. 4. Regressor and Structure Selection : Uses of ANOVA in System Identification

   Författare :Ingela Lind; Lennart Ljung; Torsten Söderström; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; Regressor selection; Analysis of variance; Nonlinear systems; Structure selection; Automatic control; Reglerteknik;

   Sammanfattning : Identification of nonlinear dynamical models of a black box nature involves both structure decisions (i.e., which regressors to use and the selection of a regressor function), and the estimation of the parameters involved. LÄS MER

7. 5. Quantum Chemical Interpretation of Protein Crystal Structure

   Författare :Kristina Nilsson; Beräkningskemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; structure; Theoretical chemistry; quantum chemistry; Teoretisk kemi; kvantkemi; protein; ComQum-X; Hess2FF; QM MM; hetero-compound; metal; oxidation state; protonation; force field; quantum refinement; refinement;

   Sammanfattning : An initial model in the crystallographic structure determination process, usually contains many errors. To produce an accurate model, one must carry out several cycles of crystallographic refinement. LÄS MER
